Final answer:
To determine the probability that a randomly selected senator has an 'other' affiliation, we would need the specific count of senators with that affiliation. Without this data, we cannot calculate the probability.
Step-by-step explanation:
The question "What is the probability that a randomly selected senator has an 'other' affiliation?" is related to the subject of Mathematics, specifically to the topic of probability. Based on the information provided, we do not have explicit numbers for senators with an 'Other' affiliation. However, Exercise 46 from the referenced statistics material mentions that 50 Republicans and 48 Democrats were elected to the Senate, along with two Independents who ally themselves with the Democrats, for a total of 100 senators. To calculate the probability, you would need specific data on how many senators fall under the 'Other' category. Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes. If 'Other' refers to affiliations other than Republican, Democrat or Independent, and if any such cases existed, we would divide the number of senators with that 'Other' affiliation by the total number of senators.
